Graham Hancock started out as a journalist and author, writing for main line British newspapers like The London Times and the Economist through the 1980’s. In 1989, he published The Lords of Poverty: The Power, Prestige, and Corruption of the International Aid Business, which earned a Mencken Award’s Honorable Mention for outstanding book journalism.
In 1992, Hancock swerved into alternative science and history with the publication of The Sign and the Seal: The Quest for the Lost Ark of the Covenant. In this book Hancock traces the Lost Ark of the Covenant from when it disappears from the Bible to its current resting place in Ethiopia. One reviewer called the work “garbage” with “no scientific merit.”
Hancock’s next book was 1995’s Fingerprints of the Gods: The Evidence of Earth’s Lost Civilization. In this volume, Hancock, basically recapitulates the theory of presented in Atlantis, the Antediluvian World. That is to say, that an advanced civilization once existed on Earth, it was destroyed and the survivors and remnants can be seen in the “sudden” advancement in cultures like Egypt and the Mayans.
The Message of the Sphinx: A Quest for the Hidden Legacy of Mankind (1996) co-authored with Robert Bauval theorizes that the Sphinx and certain other features on the Giza plateau were created in 10,500 BC. This idea is based on astronomical “evidence” that the manmade features were built to replicate and model the stars 10,500 BC.
Next in The Mars Mystery: A Tale of the End of Two Worlds (1998), Hancock supposes a common cosmic disaster that affect both Mars and Earth. He uses the discredited Cydonia “face” as evidence of Mars once having had intelligent life.
In Heaven’s Mirror: Quest for the Lost Civilization is basically a revision of Fingerprints of the Gods with some new evidence and some pictures taken by his wife, Santha Faiia. He does the same thing again in 2001 with Fingerprints of the Gods: The Quest Continues.
In 2002’s Underworld: The Mysterious Origins of Civilization, Hancock narrows his search for his mythical lost civilization to the bottom of the sea and again with Robert Bauval in 2004’s Talisman: Sacred Cities, Secret Faith Hancock explores a giant, thousands years old conspiracy that is organized religion.
And lastly in 2005, Hancock speculates that various psychotropic experiences he and the shamen have had are windows into real alternative dimensions. In Supernatural: Meeting with the Ancient Teachers of Mankind Hancock details several drug induced experiences he has had as evidence.
Throughout Hancock’s writings he explores, over and over again, the concept that some 12,000 years ago a highly advanced civilization existed on earth and was then wiped out suddenly. This civilization left behind remnants and hints in the form various monuments like the Great Pyramids and the City of Tiwanaku.
